Ummm, no. Beckham's a plus defender, but not great. There's a reason he's a second baseman. He was among the worst 3 hitting second baseman in baseball. There's no way he was more valuable than the guy who hit 40 home runs and led the league in walks.

Unless your goal is to win games. Look at the games that were decided by Beckham's successes and failures on both offense and defense and look at where Dunn's successes and failures on both offense and defense. Beckham was far from being the team's MVP, but he contributed more to the team's success than Dunn did.
